中文摘要	以1960--2005年河西走廊绿洲月平均最高、最低气温资料为基础,采用气候倾向率、5 a滑动平均、Mann--Kendall突变检验等方法对河西走廊绿洲最高、最低气温的时空变化特征和突变特点进行了分析. 结果表明,近46 a来河西走廊绿洲最高、最低气温均有明显增温趋势,最低气温增温幅度明显大于最高气温;增温趋势强弱的地域差异显著,最高气温中部>西部>东部,最低气温东部>中部>西部;四季均呈现增温趋势,冬季增温幅度最大;研究区升温突变明显,突变时间存在空间和季节差异
英文摘要	Based on the monthly averaged maximum and minimum temperatures in Hexi corridor oasis from 1960 to 2005, the characteristics of spatiotemporal variation and the abrupt change are analyzed by the methods of climate tendency rate, 5-year running means, and Mann--Kendall abrupt change test. Results are reported as follows: Firstly, the maximum and minimum temperatures increased obviously, the warming amplitude of minimum temperature is remarkably higher than maximum temperature, and the anti-symmetrical warming trends presented. Secondly, the warming amplitudes of maximum and minimum temperatures are obviously different in different regions. By the maximum temperature, the order is central part>western part>eastern part and by the minimum temperature, eastern part>central part>western part. Thirdly, the maximum and minimum temperatures increased during each season, but they are higher in winter than other seasons. Fourthly, the abrupt changes of maximum and minimum temperatures are apparent and they are different in different regions and seasons
